Stepped leaf storage process for cut cigarette tobacco processing

Abstract

The invention provides a stepped leaf storage process for cut cigarette tobacco processing. After being fed, the leaves are turned over through a four-stage vibration tank, the tobacco leaves are conveyed to a tobacco leaf storage cabinet through a conveying belt, low-temperature leaf storage (at the temperature of 18-23 DEG C and the relative humidity of 63%-66%) or high-temperature leaf storage(at the temperature of 28-33 DEG C and the relative humidity of 67%-75%) is adopted in the first half period of time of leaf storage based on the formula design requirement, and temperature and humidity conditions most suitable for the shredding working condition are adopted in the second half period of time of leaf storage. Temperature and humidity protection measures are arranged above a leaf conveying channel, the leaf storage cabinet, a discharging conveying vibration groove and the belt. The tobacco leaf storage condition with special requirements can be met, the process quality of the shredding procedure can be guaranteed, and operation is easy.

Description

technical field [0001] The invention relates to the field of shredded cigarettes, in particular to a stepwise leaf storage process for shredded cigarettes. Background technique [0002] The technological task of the leaf storage process in the production process of cigarette shreds is to make the tobacco sheet fully absorb the feed liquid, balance the moisture content and temperature of the tobacco sheet, and adjust and balance the processing time and balance between the tobacco sheet processing section and the shredded leaf section. The role of production capacity. At present, some tobacco factories in the industry have adopted a full air-conditioning control with relative humidity of 55-65% and a temperature of 20-30°C for the silk-making workshop to keep the temperature and humidity of the leaf storage room constant within the process index. Although this method of controlling the temperature and humidity of tobacco leaves in the leaf storage cabinet by controlling the t...

Problems solved by technology

Although this method of controlling the temperature and humidity of tobacco leaves in the leaf storage cabinet by controlling the temperature and humidity of the overall environment can achieve the control effect, it has the following disadvantages: the one is that the air conditioner consumes a lot of energy. A sufficiently large control system is required to ensure the temperature and humidity in the entire storage cabinet. As long as there is material in one storage cabinet in the leaf storage room, the entire air conditioning system cannot be shut down, which is not conducive to energy saving and consumption reduction of the air conditioning system.

The second is that the effect is not ideal. Because it is to control the large environment, it cannot guarantee that all storage cabinets have suitable temperature and humidity.

The third is that it is not conducive to the production organization of personalized leaf storage. If cigarette leaves of different brands and prices are stored in the leaf storage cabinet at the same time, the leaves can only be stored according to the same temperature and humidity conditions for storing leaves, which cannot meet the personalized storage requirements of the brand. leaf request

For low-quality tobacco leaves, when high-intensity leaf storage conditions are required, if there are other brands of leaves stored in the leaf storage room, it can only be solved by staggered production, which is not conducive to production organization
